restricted ftp (binded to a private net only)

["Chad A. Adlawan" <chadi@myphilippines.com>]

hello everyone,

    our web server has 2 NIC's on it, one's a public IP and the other a private 10.1.1.x.  
    can someone shed me some light as to how do i provide ftp service in that server BUT the daemon has to be visible on the 10.1.1.x network only ?

    this is because we want only ports 80, 25 & 22 to be visible from the outside.

thanks a lot,

Chadi
